Abstract

The present invention relates to a method and system to negotiation connection between an ingress endpoint and an egress endpoint associated with a network for a voice connection according to a control protocol. An egress codec is selected to satisfy a capability description of an ingress endpoint. The egress codec has an egress codec description. An ingress codec is selected to match a codec parameter subset from the egress codec description. Communication paths between the ingress and egress end-points are configured using the selected ingress and egress codecs, respectively, and the codec parameter subset.
